	%X Silica was extracted from agriculture waste rice husk
ash (RHA) and was used as the silica source for synthesis of
RMCM-48 and RSBA-16. An alkali fusion process was utilized to
separate silicate supernatant and the sediment effectively. The
CTAB/Si and F127/Si molar ratio was employed to control the
structure properties of the obtained RMCM-48 and RSBA-16
materials. The N2 adsorption-desorption results showed the
micro-mesoporous RSBA-16 possessed high specific surface areas
(662-1001 m2/g). All the obtained RSBA-16 materials were applied as
the adsorbents for acetone adsorption. And the breakthrough tests
clearly revealed that the RSBA-16(0.004) materials could achieve the
highest acetone adsorption capacity of 181 mg/g under 1000 ppmv
acetone vapor concentration at 25oC, which was also superior to
ZSM-5 (71mg/g) and MCM-41 (157mg/g) under same test conditions.
This can help to reduce the solid waste and the high adsorption
performance of the obtained materials could consider as potential
adsorbents for acetone adsorption.
